+## Automatic port allocations
+P2PRC would be in-charge to set to the ports to various TCP ports 
+opened. Due to this implementation the plugin being executed is 
+copied to the tmp directory with a unique UUID. 
+```
+Command: ls /tmp
+output: Semantic <UUID>_<Plugin Name>

+```
+Once the copy of the plugin is added to the /tmp directory 
+the site.yml file inside the appropriate yaml is modified 
+with the appropriate ports assigned to the container. 
+
+### Ex: 
+1. Create container called c1 with an automatic generated TCP port 
+   3313 (external) - 3313 (internal)
+2. Assumption of plugin p1 exists. p1 has one server which needs to 
+   be mapped to a free open TCP port in container c1. Below shows 
+   an implementation of a sample site.yml file.

+  tasks:

+      shell: sh server.sh 0.0.0.0:{{index . 0}}
+```
+Notice there is the following {{index . 0}}. {{index . 0}} does not belong to 
+Ansible but rather is a way to mention where to add the external free port 
+of the container. We use the golang [template library](https://pkg.go.dev/text/template) 
+to parse and populate the site.yml with the appropriate open ports. An array of ints 
+which consists of open free ports are sent to the site.yml. 0 in {{index . 0}} refers 
+to the index in the int array passed on. 
+
+After the port is automatically it's ready to run !
